SEALED JOINT BETWEEN A MEMBER AND A CHANNEL EMBRACING AN EDGE THEREOF.

Application filed August 8, 1923. Serial No. 656,436.

Doors for refrigerators, vaults, or other purposes are sometimes bound around the edges with channels that. embrace such edges and constitute the members that engage with the surrounding ambs or frames when the doors are closed. The door jambs or frames, co-operating with such doors, are also sometimes bound in or faced with metal channels. Where the doors should... be airlO tight when shut or, in the case of panels,

walls, or other devices, in which there should be air-tight joints, it is necessary that the joints between the channels and the members to which they are secured, should be sealed so as to prevent air from passing through the structure between the channels and the members by which they are carried.

The object of the present invention is to produce an air-tight joint between a metal channel embracing an edge of and secured to a door, a frame member, a panel, or other device, in a simple and efficient manner.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, where- 1n:

' Figure 1 is a front view of a fragment of a refrigerator door embodying the present invention; Fig. 2 is a section taken at right angles to the plane of the door, showing the channel about to be placed in position on the edge of the door; Fig. 3 is a view similar to Fig. 2, illustrating the condition after the channel has been fastened to the door; Fig. 4 is a section taken through a door and an adjacent door jamb, illustrating the door shown .in Figs. '1 to 3, together with a cooperating jamb also provided with a metal channel bounding same; and Figs. 5 and 6 are sections through a door jamb or the edge of a door illustrating a modified fastening means between the same and its channel.

For the sake of brevity I have illustrated my invention as applied only to a door and a door jamb and, for the same reason, 'I shall confine the detailed description to this particular embodiment; although it will of course be understood that my invention is applicable" to other structures where the board, panel or other member is bound with a metal channel.

Referring tothe drawing, 1 represents the body portion of a door of any usual or desired construction, a fragment of a rectangular door being shown. Embracing the edges ofthe door are rolled metal channels, two of which are shown at 2 and 3. The ends of these channels may conveniently be so shaped that their meeting ends will form miter joints, one of which is indicated at 4. The channels are soshaped that each is provided with what may be termed an auxiliary channel projecting outwardly from the bottom thereof along one side and having a width corresponding to one half the width of the main channel. When two such channels are brought together, a lap joint is formed, whose thickness 1s only 7 equal to the width of the main portion of one of the channels. The auxiliary channels on the door are indicated at 5 and each, in order to give it strength and rigidity, is filled with a strip or bar 6, preferably of 0 wood, the inner face of which forms one half of the effective bottom of the channel. Before a channel is placed on the door, there is laid against the edge of the latter a comparatively thick strip of a compressible, more or less elastic material 7, such as felt, asshown in F i 2. The channel is then slipped on the edge of thedoor and pressed inwardly with suflicient force greatly to reduce the thickness of the felt. The channel is then fixed to the door by means of any suitable fastening means. If the fastening means extended through the sides or flanges of the channel and through the door air might leak around such fastening means, 05 and therefore I prefer to employ fastening. devices which will not re uire perforations extending through the oor. Thus each flange of the channel may be fastened to the door independentlyof the other flange by means of screws 8 that are shorter than the thickness of the door. The felt tends constantly to expand and therefore insures a tight seal which will prevent air from passing underneath the flanges of the channel and past the edge of the body member of the door. 7

The felt is preferably carried continuously past the corners o the door, so that, while there will be a joint in the "channel- 110 shaped binding at the corners, there will be no joint in the felt at these points, and therefore no air can leak through.

The door jamb 10 adapted to cooperate with the door just described, may be provided with a channel 11 embracing its edge, this channel being similar to those on the doors and serving to hold a strip of felt 12 tightly compressed between the efi'ective bottom thereof and the edge of the door jamb. The projecting flange or iliary channel 13 on the door jamb ma be provided with a facing strip 14 of ru her on the side that is to be engaged by the corresponding element on the door; this rubber'being compressed when the door is closed and forming an. air-tight seal between the door and the door jamb.

In} Figs. 5 and 6 I have shown a modified form of fastenin means between the channel and the mem or to which it is attached, where such member is made of a core 15 sheathed on both sides with metal 16. The flange 17 of thechannel is secured to the door or jamb by a split rivet the ends of which are deflected by the metal sheathin on the opposite side of the structure and 0 not puncture such sheathing. The flange 18 is secured by nails 20 the ends of which are deflected by the sheathing on the opposite side of the door or jamb from that on which the flange 18 lies. The flanges are accordingly secured in place very firmly without perforating the supporting member in such a way that air can pass through.

While I have illustrated and described with particularity only a single preferred form of my invention with a single modification, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the terms employed in the definitions of memes sheet metal channel in the side.

forming the bottom thereof, filling strips in said auxiliary channels; an elastic compressible packing fitted between the effectiv bottoms of said channel members and the edges of said body, and means passing through the flanges of said channel members and into the body of the door, without passing entirely through the said body, for fastening said members to the latter.

2. A member comprising a body sheathed on both faces with metal, a sheet metal channel embracing a marginal portion of said body, said channel having an auxiliary channel in the side forming the bottom thereof, a ary channel, an elastic compressible packing fitted between the eifective bottom of the channel and the edge of said member, and means for securing the flanges of said channel to said member without producing an opening that extends entirely through said member. A

3. A door comprising a body sheathed on both sides with metal, sheet metal channels embracing the marginal portions of said body, each channel having an auxili ary channel in the side forming the bot-- tom thereof, filling strips in said auxiliary channels, an elastic compressible packing fitted between the eflectiv bottoms of the channels and the edges of said body, and means for fastening the flanges of said channels to said body without forming perforations through the latter.

In testimony whereof, I sign this specification.
